This invention relates to a weather-proof metal casement window.

It is the object of this invention to produce a weather-proof metalcasement window and this has been achieved'by means of a resilientweather strip which can be readily and simply attached to the easementframe. erably comes in the form of a strip of sponge rubber, 'one faceof which is adhesive and.

' method of assembly of the weather strip to the easement frame.

Referring more particularly to the drawing, the easement window assemblyconsists of a casement frame generally designated 1 and the casementwindow generally designated 2.- The casement frame 1 and window frame 2are of\ metal construction and the accurate only within commerciallimits it follows that the joint between the amb face 7 and the innerface 8 of the window frame is not a weather proof joint. Further, sincethe engaging faces 7 and 8 of the easement frame 1 and the window frame2 extend completely around the casement and window frames, that is,along the top and bottom as well as both sides, and since the windowframe 2 is hinged to the easement frame 1 This resilient weather stripprefas at 5 and 6, it necessarily follows that if the face 7 of thecasement 1 extending between the hinges 5 and 6 is weather-stripped by astrip that is not sufliciently resilient and distortable to giveappreciably when the window is closed that the outer edge 9 of thewindow frame 2 will be spaced from the face 10 of the easement frame 1and thus permit the rain, sleet, and air to pass through the easementfrom the outside. Hence, to obviate this difficulty the easement frame 1is weather-stripped by means of a thin strip 7 of resilient materialwhich is highly distortable and has high come-back qualities and ispreferably fabricated from sponge rubber, rubber similar to that used inrubber bands, and any other type of vulcanized rubher which has theabove mentioned qualities.

This weather strip may be generally designated 11 and consistspreferably of a continuous strip of sponge rubber 12 which is providedwith a suitable adhesive 13 on one face thereof, this adhesivepreferably having a rubber content and being of the type that willadhere both to metal and to rubber.

Preferably the weather strip 11 is wound about a mandrel 13 as shown inFig. 3. Hence, to prevent the adhesive 13 from integrating or stickingtogether, the successive convolution of a sponge rubber strip 12 andadhesive 13 is covered by a continuous strip 14 which will not adhere tothe adhesive 13. This strip 141 is preferably a fabricof the type knownto the trade as Holland cloth. The application of the weather strip 11to the jamb face 7 of the casement frame 1 is nicely brought out in Fig.3. To assemble the weather strip to the easement frame 1 thenon-adhesive cloth strip 11 is peeled back to expose the adhesive face13 of the sponge rubber strip 12. The exposed adhesive face of thesponge rubber strip 12 is then pressed against the jamb face 8 of thecasement frame 1 to which it adheres. lVhatever length of weather stripis desired is unrolled from the mandrel 13, the cloth 14 rolled back andwhen a sufficient length of weather strip has been unrolled it is simplysevered from the weather-strip roll.

The roll of weather strip is very easy and convenient to handle and owinto the simplicity of the removal of the (3 th 14 from the adhesive face13 of the weather strip 12, the weather strip 12 is readil assembled toa window casementand there ore does not require the services of askilled artisan. Owin to the high distortability and high comeackqualities of the sponge rubber strip 12, a complete seal along the topand bottom as well as the side edges of the frame 1 and the window.frame 2 can be attained without in any wise impairing the function ofthehinges 5 and 6 or preventing the win-' .dow frame 2 from beingcompletely closed in relation to the casement frame 1.

' Claims: y

1. A Weather strip for a casement window or the like comprising incombination of a strip of resilient rubber material having an adhesiveface, a mandrel upon which the said resilient rubber material strip maybe wound to form a roll and a non-adhesive strip contactin with theadhesive face of 4 the resilient ru ber material strip throughout itslength whereby successive convolu-- tions of the said weather strip areprevented from adhering one to the other.

2. A weather strip for a casement window or the like comprisingincombination of-a 3o continuous strip of sponge rubber having an adhesiveface, a mandrel about which the sponge rubber strip is wound to form aroll, and a non-adhesive fabric continuously in contact with theadhesive face of the said sponge rubber strip to prevent the sticking ofone convolution of the sponge rubber strip to the other whereby the saidsponge rubber weather strip may be readily applied to the easementwindow to weatherproof the same 7 by peeling back a portion of thenon-adhesive strip to expose the adhesive face of the said sponge.rubber weather-strip, which adhesive face may be applied to the windowcasement and the length of weather-strip required severed from the roll.

' 3. A weather strip for a window casement or the like comprising incombination of a continuous narrow strip of spongerubber, an adhesiveapplied to one face of the sponge 5 rubber strip and a non-adhesivestrip continuously in contact with the adhesive face of the said spongerubber strip whereby the sponge rubber strip may be rolled up with thesuccessive convolutions of the sponge'rubber a strip in non-stickingrelation. In testimony whereof we 'afiix our signa' tures.
